In this thread I will list known alt accounts of users. You can check this list before dealing with anyone. Please note that this is a work-in-progress list and in no way a complete overview of all alt accounts a person may own.
Any contribution to the list will be appreciated, you can see below how you should format your reports. Contributions should be made directly in the thread. Contributions which don't use the proper format will not be counted towards the 'level of awesomeness'. In order to be listed in the table of 'Top Contributors', a person requires at least 5 points towards the level of awesomeness scale.
